the code below is my attempt at creating a template allowing easy deployment of a static Alert rule to multiple Azure subscriptions. To achieve this, I am looping through an array containing the subscriptions I want to deploy to, in order to update the name of the alert and scope of the deployment.
I'm encountering the following error when I attempt to run a deployment using my code:
{"code":"InvalidTemplateDeployment","details":[{"code":"BadRequest","target":"/subscriptions/11111111-1111-1111-1111-111111111111/resourceGroups/Testing_RG/providers/Microsoft.Insights/metricAlerts/ExampleName_mytestalert","message":"Error converting value \"/subscriptions/11111111-1111-1111-1111-111111111111\" to type 'System.Collections.Generic.IList`1[System.String]'.

See inner errors for details."}
Any pointers as to how I can fix this error would be much appreciated! My code is as follows:

CodePudding user response:
Looking at the documentation:
scopes: the list of resource id's that this metric alert is scoped to. string[] (required)
So in you case you should have something like that:
scopes: [
subscription.scope
]
